A few weeks back RIM had announced that they would be giving free BlackBerry PlayBook tablets to Android developers that submitted Android apps for entry into the BlackBerry App World. And well, while that promotion was set to come to an end, it now looks like it will remain open and in effect until March 2nd. According to the details coming from RIM, they have seen more than 1,500 app submissions as of last Friday and perhaps more interesting, they have had more than 6,600 new developers registered in the BlackBerry App World storefront. That all being said, according to RIM;

“All vendors (new and existing) now have until 11:59 PM EST on March 2, 2012 to submit your application to BlackBerry App World.”
